1. Tungsten Contact Rivets Processing Requirements
With the continuous development of the automobile manufacturing industry, the requirements for tungsten contact materials are rapidly increasing. The user's requirements for tungsten contact materials are:
(1)Rod without cracks, scratches, smooth surface;
(2)Fine and uniform cross-section grains, short fibers;
(3)Good straightness, concentricity and roundness;
(4)High hardness, good impact toughness;
(5)Vapor pressure Low evaporation rate, small thermal expansion coefficient;
(6)Good and stable arc resistance.
Physical and mechanical properties of Motorcycle Horn Tungsten Rivet materials In order to meet user requirements, technicians have done a lot of work. For the splitting, brittle fracture, and uneven grain size of the cross-section during the production process of the Solid Tungsten Contact Rivets material, the rod diameter is the same. The reasons why the O degree and flatness can’t meet the requirements are comprehensively analyzed, and a series of measures are taken pertinently.
2. Electrical Tungsten Contact Rivets Material Characteristics
Tungsten is used as electrical contact or contact material, which is resistant to arc ablation; good fusion resistance; metal surface evaporation caused by electrothermal action, less transfer and consumption; strong current interrupting ability; and good wear resistance, dynamic hit performance. Compared with other metal or alloy materials, the price is low, so tungsten contacts and tungsten wafers are widely used in various fields of industry, agriculture, technology and defense.
Solid Tungsten Contact Rivets is characterized by its advantageous properties of high melting and boiling points, sufficient electrical and thermal conductivity and high hardness and density .Industrial Tungsten Brazed Contacts Rivets are mainly used in the form of brazed contact tips for switching duties that require a rapid switching sequence such as Car Horn Tungsten Contact Rivets for cars and trucks.
What's the Pure Tungsten Contact and Application ?
Tungsten Rivet or tungsten contact can be made from tungsten rod or tungsten disk.Tungsten point/contacts are for use in high voltage applications, usually where highly repetitive switching is required. Tungsten has a melting temperature of 3,380℃ which gives it excellent arc-erosion resistance.Tungsten may develop troublesome oxide films, especially when used as the anode contact in some DC applications. Therefore, pure tungsten is often used as the cathode contact, and a palladium alloy used as the anode contact. Such a combination also minimizes contact interface resistance and material transfer.
